Ready to build up your own light and fast trail or XC hardtail? Or upgrade your current frame? No better place to start than with a quality and affordable carbon frame. This XCT27 frame from DIY Carbon BIkes is top of the line for price and durability. Built with triple enforced T800 Carbon, a 31.6 seat tube for wider posts and dropper posts, and equipped with a durable and low maintenance PF30 or BSA threaded bottom bracket, this frame is for those that want a hardtail that takes the rougher lines.

This frame is designed in the style of the Felt Doctrine, which has a bit more relaxed geometry, takes up to 120mm of travel, and thicker layers of carbon for more trail style riding.

Nice bike frame, very light. . Came with a headset, and all parts (from a full suspension bike) fit on the frame without any problems . Ride quality is good for the trails I ride. Time will tell regarding durability.

Did a few hundred miles with it since July and no issue so far. Frame is great and seems sturdy. Instead of the traditional "zero mile, brand new" picture, here it is after a good morning's ride ! You can't go wrong at that price tag.

I built up 2 frames from DIY bikes and they are both awesome! The frames are finished beautifully and the paint was high quality, well worth it. I’ve built up carbon frames from other companies and been disappointed. These are superior, and my next frame will be from DIY bikes!!

I completed Leadville on this 22.7lbs beast with a XT 2x10 build for $1,400 invested. You cannot beat these frames!

I've made a few orders before from DIYCB but never a frame. Ordered this one to build a light hardtail for my 12 year old son. Frame quality is great. Internal routing was a bit of a pain, but that's expected. Definitely recommend for anyone looking to built a light carbon fiber bike and not spend lots of $$$.

built this light weight 12 speed up for my 75 year old mother. She can easily lift and transport it to ride with friends she visits. Hope she doesn’t need to ever remove/install the rear wheel as it requires manually spreading the dropouts in addition to what I find to be an already difficult task.

Great frame, did a build with EC90 Carbon Fiber seat post and handle bar. Carbon seat. Total build around 20lbs. Next upgrade will be some carbon wheels. ( From DIY CARBON BIKES ) You guys should support them they are amazing in service and products. Will also add a SRAM AXS group set and custom decals. - georglennox@gmail.com

Went for the first ride today, super stoked, is exactly what I was imagining. With the money I saved on the frame and wheels, I was able to go all XTR and a few other nice details. - smcrouse@outlook.com

The RT110 Whisky Parts Carbon Fork I ordered took about 2 and half weeks. In DIY's defense, I was getting very apprehensive and I consider myself a patient guy but Jenna and Ty reassured me that the frame was on its way even though the tracking website I was provided stated it had not even left the Asia coast. Trust them, it is on its way. The frame and fork are impeccable, no flaws and the matte black paint job is sweet. Even though the frame and fork came with axles, I was considering purchasing a couple of aftermarket axles, no need. They work perfectly as well as the seat post clamp that came with the frame and the headset that came with the forks. I provided some pictures and was going to provide my build but the website limits the character count :-( FYI-If you don't want to get frustrated routing your cables freehand, get a Park Took IR-2.1 Internal Cable Routing Kit. The frame comes with the cable housing tube (don't confuse this with a derailleur cable, the tube is there to make it easier to thread the cable through the frame but is not intended to terminate at the derailleur or seat post) for both the rear derailleur and seat post but when you thread the rear brake cable through, you will need this to make your life easier. Not impossible without it but easier with it. Also, at the exit points of the frame, there are some plastic guide ports. There are two kinds, one for the brake line and the other for the derailleur/seat post cables. You will see the difference as this was my first internally cable routed frame and there is a difference. GOOD JOB DIY (Ty and Jenna), definitely a do-over if I consider getting another build and probably in a different color this time and possibly full suspension.
